Patent number: 7363929Abstract: Cigarettes can be manufactured using modified automated cigarette making apparatus. Those cigarettes can possess smokable rods having paper wrapping materials having additive materials applied thereto as patterns. The additive materials can have the forms of liquid or paste formulations. The formulation can be applied to the paper web using application apparatus possessing rollers. A radiant dryer can be used to dry the additive material applied to the paper web. Such a system provides a source of paper web, applies additive material to that web in a pattern, dries the paper web, and winds the treated paper web on to a bobbin. That bobbin can be later used to provide a source of paper web on a cigarette making machine, which unrolls that bobbin, receives the treated paper web from that bobbin, supplies tobacco filler and manufactures a cigarette rod from the paper web and tobacco filler.Type: GrantFiled: October 9, 2003Date of Patent: April 29, 2008Assignee: R.J.

Patent number: 7281540Abstract: Cigarettes are manufactured having smokable rods with paper wrapping materials having additive materials applied thereto as patterns. The additive materials can be applied to a continuous, moving paper web on a cigarette making apparatus using application apparatus possessing four rollers. One roller has a series of pockets to receive additive formulation and to define the pattern of the formulation on the paper. The additive material can be applied to a transfer roller in roll interaction with a pick-up roller. Roll interaction of the transfer roller with an application roller causes transfer of the additive material from the transfer roller to the application roller. Additive material from the application roller can be transferred to the paper web that passes between the application roller and a back-up roller. A radiant dryer can be used to dry the additive material applied to the paper web.Type: GrantFiled: August 22, 2003Date of Patent: October 16, 2007Assignee: R.J.

Patent number: 4291713Abstract: The seam of the tubular wrapper for the rod-like filler of tobacco or filter material in a cigarette or filter rod making machine is heated by a first heating element during acceleration of the machine from zero speed to normal operating speed. When the machine reaches the normal speed, the seam is additionally heated by a second heating element whose heating action is more pronounced that that of the first heating element. The first heating element is caused to engage the moving seam when the first increment of adhesive film, which is applied to one marginal portion of the wrapper by a paster, reaches the first heating element. The second heating element is moved into engagement with the seam when the RPM of the prime mover for the filler transporting conveyor reaches a preselected value.Type: GrantFiled: January 18, 1978Date of Patent: September 29, 1981Assignee: Hauni-Werke Korber & Co.
